Problem with Managed Server pointing to a different JDK

Question

Hi,
My Adminserver is pointing to JDK 1.7 which is shown in the startup, but my managed servers are pointing to a different 1.6_43 . We are running into Java version mismatch problem while deploying our application built with jdk 1.7 onto these managed servers . How do i change the version of my managed server ?
Thanks
Sam

Hi Sam,
You generally only have to change it in two places.
DOMAIN_HOME/bin/setDomainEnv.sh and MW_HOME/wlserver_12.1/common/bin/commEnv.sh
See examples below.
If you are on Linux you can quickly fix it. For example:
cd /u01/app/oracle/product/fmw
find . -type f -exec sed -i "s/\/u01\/app\/oracle\/product\/jdk1.6.0_39/\/u01\/app\/oracle\/product\/java_current/g" {} \;
It is a good idea to make a softlink to your Java installation, then you will not have this problem in the future. If you are on Windows you can use a symlink.
Linux example:
ln -s /u01/app/oracle/product/jdk1.7.0_25 /u01/app/oracle/product/java_current
Windows example:
mklink /d D:\oracle\product\java_current D:\oracle\product\jrockit-jdk1.6.0_26-R28.1.4-4.0.1
setDomainEnv.sh
/u01/app/oracle/domains/eksudv/bin/setDomainEnv.sh
if [ "${JAVA_VENDOR}" = "Oracle" ] ; then
        JAVA_HOME="${BEA_JAVA_HOME}"
        export JAVA_HOME
else
        if [ "${JAVA_VENDOR}" = "Sun" ] ; then
                JAVA_HOME="${SUN_JAVA_HOME}"
                export JAVA_HOME
        else
                JAVA_VENDOR="Sun"
                export JAVA_VENDOR
                JAVA_HOME="/u01/app/oracle/product/java_current"
                export JAVA_HOME
        fi
fi
commEnv.sh
/u01/app/oracle/product/fmw/wlserver_12.1/common/bin/commEnv.sh
# Reset JAVA_HOME, JAVA_VENDOR and PRODUCTION_MODE unless JAVA_HOME
# and JAVA_VENDOR are pre-defined.
if [ -z "${JAVA_HOME}" -o -z "${JAVA_VENDOR}" ]; then
  # Set up JAVA HOME
  JAVA_HOME="/u01/app/oracle/product/java_current"
  # Set up JAVA VENDOR, possible values are
  #Oracle, HP, IBM, Sun ...
  JAVA_VENDOR=Sun
  # PRODUCTION_MODE, default to the development mode
  PRODUCTION_MODE=""
fi
